Speedment is a Java stream ORM developed by the team at Speedment, Inc. It is an open source tool on Github[1] that uses Java 8 streams[2] to develop relational database applications. Speedment is available as an Apache 2-licensed open-source "community edition". Speedment also licenses extensions under closed-source commercial terms[3]. Speedment is implemented in Java and accessible from software written in other languages that works in the JVM ie. Scala and Kotlin.

Technology

Speedment is a Java 8 Stream ORM Toolkit and Runtime.[9] The toolkit analyzes the metadata of an existing legacy relational database and creates a Java representation of the data model which together with the Speedment runtime allows the user to create Java applications using Java 8 streams without any specific query language or API. There is a resemblance between Java streams and SQL which is exemplified in the following table[10]

SQL Java 8 Stream Equivalent
FROM stream()
SELECT map()
WHERE filter() (before collecting)
HAVING filter() (after collecting)
JOIN flatMap()
DISTINCT distinct()
UNION concat(s0, s1).distinct()
ORDER BY sorted()
OFFSET skip()
LIMIT limit()
GROUP BY collect(groupingBy())
COUNT count()

Licensing and edition

Speedment is available as an open source and an enterprise edition. The open source edition is free but is limited to open source databases. The enterprise edition, which requires buying a license, adds on commercial databases (Oracle, DB2, DB2/400 and Microsoft SQL Server) as well as Avro-files. It also includes an in-JVM-memory data store.

Speedment, Inc.

Speedment was founded by the serial-entrepreneurs Carina Dreifeldt[11] (CEO) and Per Minborg [12](CTO) in 2010. It is a spin-off from the music service Chilirec[4], an early cloud service that gained users world wide.

Speedment, Inc,. is headquartered in Palo Alto, CA, USA in Silicon Valley.

Further Sources

Oracle Java Magazine published an article on Speedment in their May/June Edition 2017 where the title was: "Database Actions Using Java 8 Stream Syntax Instead of SQL"[13] Further the core developers also pursue their own blogs which are frequently featured on Java websites like dZone, Java Code Geek, Voxxed and more.
